The Bali Tiger likely became extinct in the 1940s (Seidensticker 1987). On the basis of skull morphology Mazak and Groves (2006) classified the Bali Tiger as a subspecies of the Javan Tiger (also extinct), which they consider a separate species Panthera sondaica. Traditionally the Bali Tiger is considered a subspecies of Tiger Panthera tigris (Nowell and Jackson 1996).

Justification:
Tigers were last positively recorded from western Bali in the late 1930s. The Bali Barat National Park was established in 1941 in tiger habitat, but it is likely that Panthera tigris balica became extinct by the end of World War II or possibly as late as the early 1950s. The causes of extinction include hunting, and loss of forest habitat and prey base. There are no Bali Tigers in captivity (Seidensticker 1987)
